Everyone Teaches AI. Few Deploy It in Real Businesses.
Courses teach prompts. Consultants make decks. Communities sell templates. Nobody gives you the actual production agents running in real businesses.
78%
of AI projects fail at deployment
Courses sell theory
I give you the actual agents powering my businesses — architecture, prompts, and config included.

production agents at launch
Templates don't work
Every agent was deployed in production first and documented after. Not the other way around.

when AiMy shadows your builds
Most communities require manual summaries
Connect AiMy to your workspace and let her shadow your builds. She autonomously generates sanitized Playbooks to share. When she does, that month is on us.
Built by the Same Person Showing You
Every agent in the ExtraDay library was born from one of these products. This isn't theory — it's production code.

I'm Not Building This Alone
Every product you just saw? I didn't build them solo. AiMy is my autonomous AI co-pilot — she runs all 9 of my businesses around the clock so I can focus on building. But she also has another role that's just as important: she's the engine behind this community.
AiMy shadows everything I build, compiles it into shareable Playbooks, and helps me scale knowledge transfer to our members. And she doesn't just work for me — she helps willing contributors in this community turn their own builds into documented, shareable knowledge too. That's how one community stays high-signal without burning out its founder.

Leading the AI-Driven Organization — MIT Sloan
Built by a CEO Who Builds With AI — Every Day
I'm Dmitry Kozko. I've taken my companies to NASDAQ, been granted 36 patents, and chaired an AI Governance committee. But that's not why I started Extra Day.
I started it because I was tired of AI communities that sell theory. I have 10+ production agents running across my businesses right now — social publishers, pricing engines, WhatsApp concierges, auto-optimizers.
Extra Day is where I share the actual agents. The architecture docs. The SKILL files. The prompts and configs. And every month, I explain what I built and how I built it — live with the community.
Latest from LinkedIn
The highlights go to LinkedIn. The raw build logs go to members.

Questions? Answers.
No. ExtraDay gives you production-ready agent skills — the actual SKILL files, architecture docs, and configs from businesses generating real revenue. Courses teach theory. We give you installable skills with auto-synced updates and changelogs.
AiMy is my autonomous agent that manages 9 businesses. As a member, you can message her directly on WhatsApp to ask about any specific build — how I solved a problem, what architecture I used, why I made certain decisions. She gives you context and learning, not copy-paste code.
The Build Feed and Weekly Briefing are written for business leaders, not engineers. You'll understand what shipped and why it matters. For skill installation, we provide step-by-step guides.
Live Build Feed with voting (top build gets a monthly Zoom deep-dive), live skill repository with auto-synced updates, WhatsApp access to AiMy for build Q&A, weekly AI briefing, exclusive founding member WhatsApp group, and the chance to showcase what you build live (and get that month refunded). Price is locked forever at $99 — it goes to $249 after the founding cohort.
Yes. Cancel in one click via Stripe. No contracts, no commitments, no questions asked. But founding member pricing is gone once you cancel.
Every time I push code across my 9 repos, AiMy auto-summarizes the commit into a community-readable dev note. Members vote on features and comment on builds. The most-voted build each month gets a live Zoom session where I walk through the code and answer questions.
LinkedIn gets the highlights. Members get the raw build logs, the installable skill files, the architecture decisions, and the ability to vote on what I build next. It's the difference between watching a cooking show and getting the recipe.
Yes — as a separate consulting engagement. The membership gives you the blueprints and community. If you want a custom AiMy deployed for your specific business, reach out through the Work With Me section below.
